Source corpus
Consecutive 10-Ks form the comparison layer. Earlier-disclosure checks use the frozen 8-K and first-substantive-headline corpora.
Methodology and trust
Plain language comes first. Technical detail is available when a reviewer needs to audit source identity, timing, extraction, or classification.
How the demonstration works
The frozen data and classifications were not altered to improve the visual story.
Consecutive 10-Ks form the comparison layer. Earlier-disclosure checks use the frozen 8-K and first-substantive-headline corpora.
Matched sections from one annual filing are compared with the issuer’s next annual filing.
Only information available strictly before the current filing can affect novelty or classification.
Same-day news is excluded to avoid uncertain ordering around the filing timestamp.
Every retained change has prior and current excerpt locations. All 1,990 offsets were validated.
A fixed deterministic score records strength of match and classification; it is not a probability of return.
Previously disclosed, genuinely new relative to the study sources, partially anticipated, or unclear.
The 150 issuer-disjoint filing pairs and thresholds were frozen before the final bounded tests.
Eight cases were chosen for evidence diversity and clarity—not later market performance.
Trust checklist
Trust is a product feature only when the evidence is visible and the boundary is explicit.
Novelty, in plain language
The label means the frozen search found no earlier match in the covered 8-K and pre-filing headline sources.
A relevant earlier 8-K or strictly pre-filing headline exists.
No earlier match exists within the frozen filings and headlines available in this study.
Earlier sources contain part, but not all, of the current disclosure.
The system cannot resolve novelty confidently; analyst review is required.
Interpretation layers
This separation prevents future information from leaking into a filing-time claim.
Prior/current filings, strictly earlier 8-Ks, and pre-filing headlines.
Change, category, direction, materiality, novelty, confidence, and evidence links.
Relevance, economic significance, model updates, and the conclusion shared with the team.
Subsequent market behavior, labeled separately and never used for classification or case selection.
Experimental Research Idea Engine
The eight-case system is suitable for demonstration, but broader generation remains blocked until formal blinded human review confirms grounding quality and usefulness.
Limitations
The product demonstration is operational; the risk analysis remains inconclusive.
The secondary archive contains 296,119 validated parsed SEC 8-K records from 2012–2024 and 731,682 frozen first-substantive-story headlines from 2015–2024. Article bodies are not redistributed. Annual partitions load only on request.
Public trust resources
Technical test coverage does not establish research validity.
